To @ZZ fav/tom 'it on ay/ concern:

Be it known that l, Fnnnnsron A. dairies, a citizen of the United States, residing at Cleveland, in the county oi Cuyahoga and State of Ohio, have invented new and useful Improvements in Rotary Cleaning Devices, ol which the following is a specification.

This invention relates to tool primarily designed for ship clearing, boiler scraping and like analogous uses, and embodies a peculiar formation of a :trame upon which a rotary tool and motor for operating the same can be conveniently disposed in workingrA relation.

rthe nature and advantages of the inven tion will be readily apparent when the fol lowing description is read in connection with the accompanyingl drawing, the invention residing in the specilic construction, combination and arrangement of parts as claimed.

In the drawing` forming part of this speciiication like numerals of reference indicate similar parts in the several views and wherein Figure 1 is an elevation of the tool con structed in accordance with my invention.

Fig. 2 is a top plan view of the frame with the motor removed.

A tool constructed in accordance with my invention embodies a trame indicated' gene erally at A and having a relatively narrow end portion constituting a support for 'the motor B, and a relatively broad end portion upon which the rotary tool C is journaled. The frame may be constructed from any .suitable materialj preferably from strap iron and including spaced members 10 and 11 respectively rihe members are twisted at appropriate points in their length as at 12, whereby 'the corresponding portions at one side of the twisted portion are disposed horizontally in close proximity' to each other to aii'ord a satisfactory base or support for the motor B. The extremities of the horizonn tally disposed portions 13 are connected by means ot a sui table handle 14. The members 10 and i1 in advance of the twisted portion 12 diverge outwardly as at 15. and are then extended in parallelism, and constitute bearings for the shaft 1G of a rotary tool. The

tool. C may be in the nature of a brush, or

a scraper constructed in the manner illus ing' of the preceding; blades. The shaft 17' of the motor B, es well as the shaft 16 et' the rotary tool C is provided with a grooved wheel 18 over which is trained a belt 19 whereby the tool C is rotated when the mo- Gil tor B is in. operation. The motor B may be of any suitable character, preferably an electric motor, and embodies among other features a base 20 provided with suitable openings and adapted to register with Opern ings 21 of the horizontal portions 13 ot the frame, for the reception of suitable fastening,- elements 22 by means of which the motor is secured rigidly to the frame. A, series of openings 21 is provided whereby the motor B can be moved toward and away from the tool C, and when moved away from the latter eiiiects an adjustment for the tightening` ot the belt 19. A handle 23 projects laterally from one side of the frame at right angles to the handle 1dwhereby the tool in its entirety can be lconveniently handled when its use is desired.

By the arrangement of the handles 14 and Q3 theicontac-,t oi"- the tool C with the surface to bo cleaned may be conveniently regulated, either. one of the handles acting as a fulcrum, so that the impact oi the blades of the tool may be greater or less as desired, the arrangement of the handles permitting this to be regulated to a nicety.

lli/'hat is claimed is rn 1. il. device of the class described comprising; frame, a combined hammering' and scraping tool rotatably mounted therein and transverse]y thereon, a motor mounted upon said iframe for operating said tobfl and han- Sil dles secured to Suid frame, whereby, the

5 cle'funng devcencluding :L frame having a motor thereon and handles therefor, of at rotary member, tangentially arrangedl combined hammering :md-scraping blades carried by said member and mounted transversely on seid frame' and driving means con- 1U meeting the motor with said rotary member.

In testimony whereof I ax myl signature.
